Bonsoir,

Voici une espèce sur tiges mortes d'Equisetum palustris trouvé au bord d'un ruisseau à 1'150m. Apothécies 0.3-0.9mm de diamètre, l'hyménium de couleur crème à brun clair, surface externe et marge couverte de poils, asques octosporés, 100-145x12.5-15µm, IKI+, spores lisses, hyalines, biguttulées, 18-20x6-7µm, paraphyses septées et élargies au sommet 5-7µm.


Merci d'avance pour vos avis.


Elisabeth

Peut-être du côté des Cyathicula / Crocicreas.

Re : Sur Equisetum
oh this is great. It is ERD-5313. Pineda (Somiedo). Enrique Rubio made a nice plate of a sample on Equisetum ?arvense from Asturias. It could be that this species is related to Stamnaria poeltii, an undescriped species. If we had sequences of 5313 we would know more. S. poeltii turned out to be unrelated to Stamnaria. I suppose that Danny Haelewaters is interested in your collection regarding DNA.

Re : Sur Equisetum
Very nice, in fact, the fruit bodies looks like Rubio's pictures, idem the microscopic character. For the DNA, the material would be sufficient. Thank you very much Zotto.

Re : Sur Equisetum
Hello Elisabeth and Zotto,
i just accidentially looked at this message.
The substrate here clearly does look like E. arvense, not E. palustre, despite i do not see all characteristics of the host clearly.
I am not sure if my named "St. poeltii" will or may grow on this host as well, but got my doubts so far, thus would certainly hesitate to say both could be conspecific.
However, genetic comparison will be useful to clear relations.

Liebe Grüße 

Erwin

Re : Sur Equisetum
Hi Erwin & Elisabeth
the difference in croziers vs. simple septa and in spore contents, also in apo colour (flesh vs. yellow-orange), suggest different species.

It would be great if the Equisetum could be clarified to species.  Are there more pics of the plant?

Re : Sur Equisetum
Erwin is right, it's E. arvense.

Voici deux autres photo, malgré tes doutes, je pense que c'est cette espèce.
